I am installing my apex-i downpipe (which eliminates the cat.) and when i take the stock downpipe off what do I do about the cat. converter ground wire, do i take that off too or do i ground it to somthing else?
Do the 1gs have this too? I know there is a steel wire/shoelace type thing that is connected to the downpipe in front of the catalytic converter. I'm not sure if mine is connected.... and I now have a check engine light and an a/f gauge that reads the last green RICH LED.
I didnt connect mine and my mileage is fine, if not better, with the straight through stuff on. I have developed a CEL, but I doubt thats related to the grounding wires. I dont want to weld that shit on my SS pipe, but putting it on the clamp souds like a good idea.
Is it a ground for the 02 sesnor? That would explain the constantly full rich A/F gauge. I think when I took my car in to have the head rebuilt they cut it off..... cuz it doesn't dangle anymore but it's not grounded anywhere. I'll have to double check, but I'll get back to you.
